What is a QR Code?
QR Code (Quick Response) is a matrix barcode (2 dimensional barcode) which allow its contents to be decoded at rapid speeds. QR Codes were originally used for tracking of vehicle manufacturing, now they are used in applications aimed at mobile phone users.
Smart phone users can download applications which scans the code with the phone’s camera. Once the mobile user has scanned the QR code which are found in magazines, billboards, business cards or packaging – it will reveal text, contact information, phone numbers or open a webpage in the phone’s browser. This instant link to the code’s origin and its message is an interactive marketing sensation.
Here are two ways to decode QR Codes on your computer:
ZXing (pronounced “zebra crossing”) is an application that primarily allows smart phones users to take picture of QR code and decode it on the device itself, without connecting to the internet. It also has an online decoder where you can upload an image or provide a link to the image of the code and decode it.
